Application filed December 27, 1913. Serial N 0. 8 09.033.

'1? all 107mm it may won/m n Be it known that I, WALTER P. Mnurrrr, acitizen of the United States, residing at hicago, in the county of Cookand State of enlarged detail front elevation of the pinlever. Fig. 7 isa detail sectional view on the irregular line .7-7 Fig. 2, the leversbeing removed looking in the direction of the arrows. Fig. 8 is a frontelevation of a release rigging embodying my invention, attached to acar, adapted to operate a bottom operating coupler. Fig. 9 is a top planview of Fig. 8. Fig. 10 is a. top plan View of a release rigging showinganother embodiment of my invention, Fig. 11 is a front elevation of Fig.10. Fig. 12 is a detail top plan View of a modified form of fasteningbetween the ends of the levers. Fig. 13 is a detail top plan view of thelevers showing still another type of fastening between the ends of thelevers. Figs. 14, 15 and 16 are, respectively a top plan, an end and afront elevation of the hand lever fulcrum.

The reference numeral 1 designates a car, broken away, 2, the draw bar,3 the coupler lock pin and 4 the end sill.

In carrying out my invention it. will be understood that I do not limitmyself to the exact; application of the fulcrums as show-n. as this isgoverned. to a great extent, by the design oifthe car. i

I he pin lever fulcrum 5 has an integral base 6 which is secured to theend sill by means of the rivets 7 as more clearly shown in Fig. 7. Thefulcrum 5 has at its outer end an elongated bearing 8 terminating in ashoulder and a screw threaded portion on which the washer 9 is securedby means of the nut 10, the washer bearing against said shoulder.

The fulcrum 11 for the hand operated lever is provided with an integralbracket 12 which is secured by means of the rivets 13 i (one only beingshown) to the base flange of the channel end sill.

Patented Aug. 24, 1915.

14 is a washer and 15 a nut on the outer end of the bolt 16, said boltpassing through one legof the bracket and through the fulcrum. r

The hand lever 17 is pivotally mounted on the. fulcrum 11 and securedthereon by means of the washer-14, bolt 16 and nut 15: the outer portion18 of the hand lever 17 is offset forwardly from the remainder thereofand when in operative positionon the car is beneath the plane ofthe'under face of the car as clearly shown: theinner portion of the headFever; 1? Ts deflected upwardly at an angle to the remainder andterminates in an elongated bearing pin 19 having an offseteiad-fllseiving as a stop to retain the lever 21 on the bearing pin 19.Th1s hearing 19 extends forwardly from the car when the lever is securedto the car.

fulcrum 5 heretofore described in detail.

connected with the locking pin 3 as shown. The outer end portion of thepin lever 21 is,

1n the preferred form, provided with an elongated slot 22, in which thebearing pin 19, of the hand lever, is journaled or positioned, so thatwhen the hand lever is pulled upward, its inner end is swung downwardand by reason of the independent fulcrums of the two levers and the pinand slot connection between said levers, an upward movement of the innerend of the pin lever In Figs. 10 and 11 I have shown the outer end ofthe pin lever 23 and the inner end of the hand lever 24 connectedtogether by means of the bolt and nut 25 there being a its ends, on theelongated bearing 8 of the.

vlhe inner end of the lever is operatively slot 25" in one of the leversindicated by dotted lines whereby apin and slot connection is formedbetween the levers. In Fig. 12 I the bearing 26 of the hand lever 27prohave shown the outer end of 6 be provided with the beari 1'' end othe car, I

bearing on the hand operated lever on whlch vided with a nut 28 threadedthereon, said nut acting as a stop to retain the pin lever '29 on saidbearing.

As shown in Fig. 13 the in lever 30 may I g pin 31 and the hand lever 33provided with the elongated slot 32, to provide the pm and slot connec-'tion" between the two levers.

I claim If '1. In a release rigging for car couplers,'a-

vertically movable pin operating lever pivote'd to a car intermediateits length to provide bodily movement thereof to and from said'ear, of ahand operated lever pivoted intermediate its length to a car, and aconnection between the adjacent ends of said levers, said connectionproviding an elongated pivotal bearing of one of saidlevers on the v.outer of said levers,'whereby said bodily 2- movement of said pin leveris permitted.

2. In an uncoupling rigging for car couplers, a hand operated leverpivoted intertmediate its ends on the end of car, a pin lifting leverpivoted intermediate its ends Q on the 'end of the car, an elongatedpivotal bearin for said pin lever, secured on the and an elongatedpivotal the outer end of the pin lever is mounted whereby the pin leveris free to move bodily toward and away from the car to accommodate themovement of the coupler in bufiing anddraft. f '3. 'In anuncouplingrigging for car canmounted,

plers, the combination with a pin lever pivotally mounted intermediateits ends, on the end of a car, of a hand operated lever independentlypivotally mounted intermediate its ends on the end of the car, the innerend thereof being deflected upwardly to the 40 plane of the pin leverwith which it has a. pin and slot connection, the outer portion of thehand lever being out ofthe plane of the remaining portion andsaggingdownwardly and forwardly, anddisposed, when not in operation,beneath the plane of the under face of the car, and adapted to be movedupwardly to operate the pin lever.

4. In an uncoupling riggirig for car couplers, a hand operated leverpivotally intermediate its entls, on the end of a car, and having itsinner portion terminating in an elongated pivotal bearing for a pinlever, an elongated pivotal bearing secured to the end of a car, a pinlever p1v- 5'5 ing on the hand lever is journaled, whereby the pin levermay move bodily with the coupler in bufiing and draft. In testimonywhereof I aflix my signature in presence of two witnesses.
